7.2 Connecting Low Voltage Wiring—Optional
Low voltage connections to the Liebert XDV are available only on units with the optional condensate
detection feature. The low voltage connections are on the right side of the electrical connections box,
just above the power connections (see Figure 35). These dry contacts can to be connected to a moni-
toring unit, such as Liebert’s SiteScan®.
For units equipped with condensate detection, make low voltage connections according to site-specific
drawings. The unit must be installed in accordance with national wiring regulations.
